path Specifies the directory to make the current directory.
If Command Extensions are enabled the PUSHD command accepts
network paths in addition to the normal drive letter and path.
If a network path is specified, PUSHD will create a temporary

any temporary drive letter created by PUSHD when you POPD that
drive off the pushed directory stack.
